Fire Sprinkler Contractor License

No Illinois License, No Fire Sprinkler Work

No person or business may design, install, alter, repair, or maintain automatic fire sprinkler systems in Illinois without a valid OSFM license (225 ILCS 317/12). The Illinois Office of the State Fire Marshal (OSFM) administers licenses under the Fire Sprinkler Contractor Licensing Act (225 ILCS 317) and 41 Ill. Adm. Code Part 109.

$3,000 Application and Biennial Renewal — Late Costs $3,500

The initial license and each biennial renewal cost $3,000 (41 IAC §§ 109.150(a)(1)(A)–(B)). Filing late — even one day after expiration — triggers an immediate $500 reinstatement fee for a total of $3,500; there is no grace period (§ 109.100(d)). If a license goes unrenewed for more than one year, it terminates and a new application is required (§ 109.100(f)).

NICET Level III Certification Required

The application must include proof that the contractor's designated certified person holds a current NICET Level III or higher certification in water-based fire protection systems layout, or a valid Illinois Professional Engineer license (41 IAC § 109.40(d)(1)(B)(i)). NICET Level II is not sufficient for this designation.

16 CE Hours per Cycle — 8 Each Year

The designated certified person must complete at least 16 hours of continuing education per biennial license period, with a minimum of 8 hours during each year of the current license (41 IAC § 109.40(d)(2)(A)).

Insurance: $1,000,000 Liability and Statutory Workers' Compensation

Fire sprinkler contractors must carry liability insurance of at least $500,000 per person / $1,000,000 per occurrence for personal injury, plus at least $1,000,000 per occurrence for property damage (41 IAC § 109.40(d)(1)(C); 225 ILCS 317/35). Workers' compensation must comply with the Illinois Workers' Compensation Act (820 ILCS 305).

Penalties: Suspension, Revocation, or Administrative Fines

Unlicensed fire sprinkler contracting violates 225 ILCS 317/12. OSFM may suspend, revoke, refuse renewal, or assess administrative fines under 41 IAC § 109.120.
